Background technique

At present, the combination locks in the prior art are classified into electronic combination locks and mechanical combination locks, and electronic combination locks or smart locks include fingerprint locks, card locks, irises, and Facebook recognition. It is undeniable that all electronic combination locks or smart locks have a common disadvantage: the higher the degree of electronicization, the lower the reliability. Such as fire, humid climate environment, fear of vibration and electrostatic shock, fear of electromagnetic interference; need to consider the power supply of the mains or battery, technical unlocking tutorials and tools are sold everywhere online, criminals can easily master the skills of technical unlocking . In summary, people can never predict when the electronic function will fail, maybe in the next second, power outages, short circuits, electronic cracks, etc., will make the door lock useless at any time.

Mechanical password locks also include password-enabled password locks and password-less password locks, especially mechanical password-locked password-less locks. Due to the limitations of existing mechanical password-locking mechanisms, the change pattern of passwords is too simple. You have some understanding of the structure of the password. You can lock and open the password in a limited number of trials by listening, operating the touch, etc. If you know the internal structure, you can easily open the password lock through repeated attempts. Therefore, a combination lock with simple structure, safety and reliability, and strong anti-theft is an urgent problem to be solved at present.

technical problem

The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a keyless blind mechanical password lock with simple structure, safety and reliability, and strong anti-theft property.

Technical solutions

The technical solution adopted by the present invention to solve its technical problems is: a keyless blind-open mechanical combination lock, which is characterized by comprising a vertical plate, a bottom plate, a turntable, a plug-in disk and a rotary shaft, and the coaxial set of the turntable and the plug-in disk is rotating On the wheel shaft, the runner shaft is horizontally installed on the vertical plate. One end of the runner shaft passes through the vertical plate and the end portion is set with a password wheel. The inner end of the password wheel passes through the vertical plate and is connected to the turntable. The inner end surface of the receiving plate is provided with horizontally disposed pins, and the plugging plate is provided with a plurality of forward and reverse slots correspondingly; a turntable positioning mechanism is arranged on one side of the turntable, and the inner surface of the turntable is provided with the inner side of the turntable positioning mechanism. Docking mark card slot; a positioning insert plate is provided between the opposite end surface of the inserting plate and the turntable, and the bottom of the inserting plate is fixedly connected to the bottom plate, and a plurality of inserting holes are annularly arranged on the inserting plate, and the plug pins pass through the corresponding inserting holes Connect the forward or reverse slot of the patch panel.

The present invention changes the structure of the lock core of the traditional mechanical combination lock. The coaxially stacked turntable and the plug-in disk are connected to each other to complete the opening and locking of the lock core. The turntable is used as a selection disk and the plug-in disk is used as a selected disk. The turntable is provided with horizontally-located bolts, and a plurality of slots are correspondingly provided on the plug-in disk. The plugging relationship between the plugs and the slots can be turned on or off. In order to improve the security of the mechanical combination lock and the anti-theft performance, the slots are divided into Forward slot and reverse slot, the plug passes through the positioning plug board to connect the plug tray, the positioning plug board is provided with multiple plug holes, the plug holes are arranged in a ring, corresponding to multiple slots, preferably, the plug holes There are more than the number of slots, that is, there are cases where the pins can be inserted into the slots, and there are also cases where the pins cannot be inserted into the slots. When an opener who does not know the password wants to try to open the mechanical password lock, if the latch corresponds to a reverse slot, the plug-in disk will be reversed.

Because the dial and scale mark of the traditional password lock are not on the appearance panel, the method of replacement is changed to a mark card slot and an elastic positioning protrusion. The movement between the two has a regular stuttering feeling. At this time, the illegal opener Even if you are familiar with the internal structure of this combination lock, but you can't see it, you will be at a loss when facing several circles of slots and several forward and reverse slots in the plug-in disk. . The present invention is designed to correctly turn on the password in an upside-down and disorderly manner, which can be set arbitrarily. In this way, the inertia thinking of trying to open the combination lock is completely disrupted, which makes it difficult to open the combination lock at the same time; at the same time, a positioning mechanism is also set on the side of the turntable. Only the positioning mechanism is aligned with the mark card slot on the turntable and a corresponding one is found. 2. When the card slot is marked correctly, it can be inserted correctly only through the cooperation of the positioning mechanism. In particular, when the combination lock of the present invention is opened, no matter the password is right or wrong, there is no difference in sound and touch. Therefore, illegal openers cannot You can judge the regularity and correctness of the password by turning the sound or touch. Even if you peep at zero distance, you cannot know the correct opening position. Furthermore, the position and order of the forward slot and the reverse slot on the plug-in disk are arbitrary, and the spacing between them is not the same, which can once again improve the security and anti-theft performance of the combination lock.

The turntable includes a ring of an outer ring and a plurality of turntable ribs evenly distributed in the ring, and one end of the bolt is horizontally fixed on the turntable rib.

The purpose of arranging multiple turntable ribs is to serve as a backup installation position for the bolts. When the bolts at one position fail, the bolts can be installed on other turntable ribs.

The turntable rib is provided with a cavity therein. Both sides of the turntable rib are provided with an adjustment slot for allowing the bolt to move radially, and an adjustment mechanism for driving the bolt to move radially is installed in the cavity.

The purpose of setting the adjustment slot is to facilitate the adjustment of the position of the pin in the radial direction of the turntable. When the combination lock is closed, the position of the pin can be adjusted to the wrong position, so that the position of the pin and the slot are completely staggered and are in different diameters. Within the circle, even if an illegal unlocker guesses a part of the password, the password lock cannot be opened from the outside. Only by adjusting the latch to the set position can it correspond to the position of the plug-in disk with the correct password; Multi-turn sockets can also be set on the plug-in disk, which facilitates the formation of multiple sets of more complex passwords and maximizes the security of the password lock.

The adjusting mechanism is a rack and pinion transmission mechanism, which includes a gear mounted on a rotating shaft and a rack which is erected on the inner cavity of the turntable rib. The upper part of the rack is fixedly connected with a latch and the lower part engages the gear.

Preferably, the plug-in disk can be provided with a plurality of sets of forward and reverse slots of the inner and outer coaxial sets, and a plurality of turn-marking slots on the outer circumferential end surface of the turntable correspondingly.

The plug-in disk is provided with a plurality of sets of forward slots and reverse slots. Both the forward slots and the reverse slots are grooves with inclined surfaces, and the inclined directions of the forward slots and the reverse slots are opposite.

The oblique direction of the forward slot and the reverse slot is opposite, so that the latch enters the forward slot to drive the plug-in disk forward, and the latch enters the reverse slot to drive the plug-in disk to reverse, avoiding multiple attempts to open the password without knowing the password lock.

The number of the forward slots is consistent with the number of digits of the set password.

The turntable positioning mechanism includes a positioning support, a rotating shaft, a positioning wheel, and an eccentric positioning roller. The positioning support is fan-shaped, coaxially disposed on one side of the turntable, one end of the shaft passes through the vertical plate and connects to the positioning wheel, and the middle of the shaft is provided. There is an eccentric positioning roller. The other end of the rotating shaft passes through a positioning bracket to connect a limiting mechanism that limits its rotation angle. The eccentric positioning roller is provided with a tangent plane. The end of the positioning bracket near the turntable is provided with elastic positioning protrusions. One end of the positioning protrusion is engaged with the mark card slot, and the other end is provided with a positioning spring, and the positioning spring is elastically connected to the eccentric positioning roller.

The eccentric positioning roller is provided with a tangent plane. By rotating the rotating shaft and the eccentric positioning roller installed in the middle of the shaft, the eccentric positioning roller with the tangent plane suppresses the elastic positioning protrusions, forcing the inner end of the elastic positioning protrusions to be pressed outside the turntable. The peripheral edge of the edge is convenient for finding and engaging with a suitable mark slot.

The turntable positioning mechanism can be provided with multiple groups around the turntable, and each group is provided with elastic positioning protrusions. The structure settings of multiple sets of turntable positioning mechanisms are exactly the same. The head of the household can choose any one of them to find the mark card slot corresponding to the correct insertion slot according to the set password rule. The purpose of setting up multiple sets of turntable positioning mechanisms is to mix food and audiovisual. The purpose of misleading random unlockers is to further improve the security of the combination lock.

The mark card slot includes multiple groups, and the number of the mark card slots is consistent with the number of digits of the set password, and each password corresponds to a set of mark card slots.

The outer edge of the plug-in disk is provided with a reset mechanism. The reset mechanism includes a reset lever, a reset bracket, and a reset slider and a reset spring installed inside the reset bracket. The reset slider is provided with two sets of left and right, and the middle of the two sets of reset sliders. A reset compression spring is connected between the two, a tail extends out of the reset bracket, and a fixing block is arranged outside the reset bracket, and the fixing block is arranged between the two sets of reset slider tails.

After being arbitrarily rotated for many times, when the turntable and the plug-in disk have no idea where they are, the plug-in disk can be reset by the reset mechanism and restored to the initial position, which is convenient for quickly opening the code lock with the correct password.

The two sets of reset slider tails are connected and drive two sets of tensioning mechanisms that move toward each other. The tensioning mechanism includes an upper pulley, a rope, a sheave, and a sheave support. The sheave support is fixed on the bottom plate. The supporting sheave is rotated and mounted on the support, and one end of the pulling rope is wound on the sheave, and the other end is connected to the tail of the two reset sliders after bypassing the upper pulley installed on the end face of the plug-in disc. A reset wheel can also be installed on the stand.

During the illegal opening process, there is no difference in sound or touch when the forward and reverse slots and the reset mechanism are actuated. Even if the illegal opener pulls or rotates the reset mechanism during the opening process, the reset mechanism is reset and illegally opened. The user also does not notice whether the slot inside the combination lock corresponding to this action is forward or reverse. Therefore, it is ensured that an illegal opener cannot open the mechanical code lock of the present invention by means of judgments such as diagnosis, touch, and digital logic analysis.

The turntable 6 is provided with a horizontally-located bolt 12 on the inner end face of the plug-in disc 7. The plug-in disc 7 is provided with a plurality of forward slots 703 and reverse plugs. Slot 701; a positioning insert plate 13 is provided between the end faces of the insertion plate 7 and the turntable 6, the bottom of the positioning insert plate 13 is fixedly connected to the bottom plate 2, and a plurality of insertion holes 1301 are annularly formed on the positioning insert plate 13, and the pin 12 passes through The corresponding plug hole 1301 is connected to the plug tray 7.

The pin 12 passes through the positioning plug plate 13 and is connected to the plug tray 7. When the positioning plug plate 13 is provided with multiple plug holes 1301, the plug holes 1301 are arranged in a ring shape, corresponding to multiple slots. Preferably, the plug holes 1301 The number is greater than the number of slots, that is, there are cases where the pin 12 can be inserted into the slot, and there are also cases where the pin 12 cannot be inserted into the slot.

The positioning insert 13 is used to limit the directional insertion of the pin 12. If there is no stationary fixation of the positioning insert 13, the turntable 6 is advanced forward. Even if the pin 12 is inserted into the slot in the plug tray 7, the turntable 6 will rotate with the slot. Twist the code lock one by one and turn it on. The function of the positioning plug plate 13 is to restrict the plug pin 12 from being inserted into the slot at a fixed position, and to push the plug-in disc 7 to achieve forward and reverse rotation.

The forward slot 703 and the reverse slot 701 only describe the relative positional relationship and reverse setting characteristics of the slots in two different directions, and do not necessarily mean that the correct combination of the password lock opening slot and the correct insertion direction The slot can be set clockwise or counterclockwise. The wrong slot is the slot set in the reverse direction.

Under the restriction of the fixed block 1005, the reset lever 1001 is restored to the set initial position. The pullable end of the pull rope 902 can protrude from the outside of the cipher lock housing, or can be embedded in the housing by other means. When the pullable end of the pull rope 902 protrudes from the outside of the cipher lock housing, it can be correspondingly located in the housing. In the present embodiment, a rotating wheel connected to the end of the pulling rope 902 is provided on the vertical plate 1 in this embodiment, and the tightening or loosening of the pulling rope 902 is realized by rotating the rotating wheel.

Working process and working principle: When opening the combination lock of the present application, it is necessary to ensure that the insertion slot is in an initial position, and rotate the positioning wheel 1105 of the turntable positioning mechanism 11 to determine the tangent plane on the eccentric positioning roller 1106 to suppress the elastic positioning protrusion 1108. , Forcing the inner end of the elastic positioning protrusion 1108 to be pressed against the outer edge of the turntable 6, and turning the code wheel 3 to drive the turntable 6 to rotate, so that it is easy to find a suitable mark card slot 601 and fasten with it, according to the password When the digit wheel 3 is turned to the correct number of the mark card slot 601, the elastic positioning protrusion 1108 of the turntable positioning mechanism 11 is buckled in the corresponding mark card slot 601. At this time, the cipher wheel 3 is pushed and passed The cipher wheel 3 pushes the turntable 6 toward the plug-in disc 7. At this time, the pin 12 is inserted into the forward slot 703 through the plug hole 1301, and the plug-in disc 7 rotates forward at an angle; once again, the turntable 6 is pulled by the cipher wheel 3 to make it Restore the original position so that the pin 12 is disconnected from the connection plate 7 and turn the code wheel 3 again, so that the next correct mark card slot 601 can be easily found and fastened to it, thereby determining the next correct password again. . As a result, repeated operations can be used to unlock the combination lock based on a known password.

When an illegal opener faces several slots and several forward and reverse slots in the plug-in disk, there are only a few forward slots 703, and the remaining 701 slots are several times the forward slots 703. Even dozens of times; at this time, the illegal opener will be at a loss and can only tempt one by one and lap by lap.

The slot set in the plug-in tray 7 is a number of turns, and each turn has a number of 701 slots in the forward and reverse directions. The position and order of the forward slot 703 in the plug-in tray 7 can be arbitrarily reversed. Open the schematic diagram:

4 3 2 1 0 0 1 2 3 3 4

Negative ————— 0 ————— Positive

When the first guess is wrong, the reset lever 1001 goes back to minus 1 and continues to go wrong until it goes back to minus 4. The first time you guessed right, the second time you may not guess correctly, the second time you guessed wrong, the reset lever 1001 returned to 0, continued to make mistakes, and continued to retreat. Guess right the second time, guess wrong the third time, return, continue wrong, continue to return. Guess wrong for the fourth time, return, and then go back again until you return to minus 4.

Illegal unlockers rely on diagnosis and hearing to open the traditional mechanical combination lock. The present invention addresses this problem by adopting the technical solution:-the sound of the latch is the same when it contacts and pushes forward slot 703 or reverse slot 701. Turntable 6 No matter which direction the reset lever 1001 is in the forward or reverse direction, the reset mechanism 10 operates with the same sound during reset.

During the illegal opening process, there is no difference in sound or touch when the forward and reverse slots and the reset mechanism 10 are in action. Therefore, the illegal opener cannot open the computer through judgment methods such as diagnosis, touch, and digital logic analysis. Invented mechanical combination lock. In short; the arrangement of the slot of the combination lock is not in the concept of numbers and mathematical logic. Even if the illegal unlocker is familiar with the internal structure of the combination lock, trying to guess and analyze the combination lock is futile.
